Data Sheet Li-ion/Li Polymer Battery Charger AUR9801C General Description The AUR9801C is a highly-integrated battery charger for single-cell Li-ion or Li-polymer batteries capable of operating with an input voltage reached 2.5V. It is a complete charger device designed to work with an USB port or 5V output AC adapter. The AUR9801C operates with CC (constant current) mode and CV (constant voltage) mode profiles. A low-current preconditioning charge mode is also provided as a trickle charging operation. The charge current is programmable up to 1A with an external resistor or a logic input. The charge voltage is 1% accurate over the full application range.
